OHIO.

Original No. 1,518,236, dated October 28, 1924, Serial No. 610,143, filed January 2, 1928. Application for reissue filed April 25, 1925. Serial No. 25,925.

To all whom it may concern:

Be it known that I, HAROLD J. Gross, a citizen of the United States, and resident of Nashua, in the county of Hillsborough and State of New Hampshire, have invented a new and useful Machine for Making Boxes, of which the following is a specification.

My invention relates to box making machines and particularly to machines for making paper boxes, its object being to improve the construction and mode of operation thereof and to provide a machine of this class which will expeditiously and efficiently convert fiat blanks into finished boxes or box sections.

To these ends my invention consists of a box making machine having the peculiar features of construction and mode of operation set forth in the following descri tion, the novel features of the invention eing particularly pointed out and defined in the 'claims at the close thereof.

In the accompanying drawings:

Figure 1 is a plan view of a box making machine constructed in accordance with my invention, detents 501 being omitted.

Figure 2 is a side elevation of the machine shown in Fig. 1.

Figures 3, 4 and 5 complete a longitudinal central vertical sectional view of the machine shown in Figs. 1 and 2.

Figure 3 is a sectional detail on line 3- 3 of Fig. 3.

Figures 6 andTare details hereinafter described.

Figure 8 is a partial elevation of the right hand end of the machine shown in Figures 1 and 2.

Figure 9 is a section on line 9-9 of Figure 8.

Figures 10 and 11 are details illustrating the operations of the folding plungers hereinafter described.

Figure 12 is a plan view of the box blank.

Figures 13, 14, and 15 are details hereinafter described.

Figure 16 is a side view of one of the wiper plates hereinafter described.

The box blanks A are fed sidewise into the machine from an inclined hopper 1 within which they are arranged in feathered relation as indicated in Fig. 3, said blanks being ur ed downwardly by gravity into position to e engaged by a pair of feed rolls 2 and 3. Each roll 2 has rubber pads upon its periphery at one point which, during each revolution of the rolls 2, enga e and feed forward the lower top-most blan Each lower presser roll 3 is carried by an arm 4 that is urged by a spring 4 toward the upper roll 2. When a blank is fed between the rolls 2 and 3 it comes into position upon two rails 5 that sup ort a pair of endless chains 6 mounted within grooves provided upon the top sides of said rails 5. These two rails 5. are supported by two cross-bars 7 9, forming part of the frame of the machine, with provision for movement thereon toward and from each other. A pair of screws 80 engaging threaded holes provided through each rail 5 hold the latter in adjusted position upon cross-bars 79 and provide means by which the rail may be adjusted toward and from the center line of the machine. Each screw 80 is made with a square outer end to which a wrench or crank may be applied by which it can be rotated. Each pair of screws is connected by a chain 81 so that rotary movement imparted to one screw of the pair is transmitted to the other screw. Adjacent the hopper 1 each rail 5 has mounted thereon a sprocket 82 around which the chain of that rail asses. Within a yoke or fork at the opposite end of each rail the grooved hub of another sprocket 83 is confined, said hub being splined upon a shaft 73 so as to be movable lengthwise thereof with the rail 5 when the latter is adjusted upon its supporting bars 79. This shaft 73 is connected b gears 74, a sprocket 75, and chain 76 with a sprocket 84 fast on the continuously driven main cam shaft 42 of the machine. The slack of each chain 6 is taken 11 by means of an idler sprocket 85 carried y an arnf 86 secured, with provision for angular adjustment, to a stud 87 pro 'ecting from the adjacent rail 5.

E ach chain 6 is constructed with pins or occupy a straightposition upon the chains,

to straighten the same. Immediately after the blank has been picked u and straightened by two of the pins 0 the chains 6, blank-positioning or ustifying members 7 are simultaneously moved toward each other and against the ends of the blank so as to center the latter should it be out of place laterally. Members 7 are a/(h'ustably secured to slide bars 8 and 8, respectively, that are moved simultaneously endwisein o posits directions by" a spring 9 and a we go 10. The wedge 10 is part of a lever 11 fulcrumed at 12 and carrying a cam 1'01? 13 cooperating with a cam 14 on the feed shaft 15. The feed shaft 15 carries a sprocket 88 connected by a chain 89 with a sprocket 90 fast on a shaft 20, said shaft being continuousl driven from the main cam shaft 42 throug a sprocket 91, fast on main cam shaft 42, a chain 92 and a sprocket 93 fast on said shaft 20. Thecam 14 is timed to cause the wedge 10 to move the two slide bars 8 oppositel in directions to carry the positioning mem ers 7 toward and against the ends of the blank just after the latter has been engaged by a pair of pins onthe carrier chains, said wedge cooperating with rolls 119 carried by the slide bars. 1

U 11 leaving the side-wise adjusting mem ers 7 the end flaps A of the'blank ass under breaker rolls 16 which bend said aps down alongside of stationary shoes 151 which support end portions of the blank immediately inside of the flaps A. This pro duces sharp folds at a. While the flapsA' are held down by the rolls 16, they ass side pressing rolls 1 which complete t e folds a. Each breaker roll 16 is supported by an arm 94 adjustably fixed upon a stud 95 prgecting from the adjacent rail 5.

ach roll 17 is carried by a bracket that is adjustably fastenerL to a stud 97 also projecting from the adjacent rail 5; Thus when the rails 5 are adjusted laterally toward or from each other the rolls 16 and 17 move with them. v

After leaving the rolls 16 and 17 the chains carry the blank under the continuously rotating shaft 29 carrying two pairs of arms 21 and 22. These are timed so that the arms 21. fold the flaps B down alongside the rails 5 while the arms 22 fold the 'fia s B down alongside of said rails, leaving t e middle double flap A A undisturbed. While thus held folded down by arms 21 and 22, each pair of flaps B and B passes into position first between a deflector 96 and the adjacent rail 5 and thence between the side of a glue pot 23 and the adjacent rail.

Thus these two fla are held out o posit1on to contact wit the glue-apply g roll 24 of pot 23. Each deflector 96 is a plate of sheet metal fastened to oneend of the adjacent glue pot 23 so as to engage the blank as it ,approaches the latter, said deflector having cooperating with it a presser foot 97 consisting of a spring arm one end of which is rigidly fastened to the frame of the ma chine with its free end bearing yieldingly against the to of the deflector immediately inside of an e evated side portion 98 of the latter. See Figs. 13 and 14. As each double end flap A A of the blank passes over the deflector 96 in its path the spring presser arm 97 engages said double flap about on the line of thefold a while the end section A of the said intermediate double flap rides against the elevated portion 98 of deflector 96. As a result the two sections A and A are swung relatively on the fold a in a direction opposite to that in which they are moved relatively by the breaker wheel 16 thereby making the joint at the foldu. very flexible in preparation for the folding operations that occur later. After leaving the de fiectors 96 the double end flaps A A pass over glue applying rolls 24 by means of which glue is applied to the under sides of said flapsp The flaps are held in contact with the glue rolls by presser rolls 25. Each presser roll 25 is carried by an arm 99 pivotally mounted upon a stud 26 and urged towardthe roll 24 by a spring. a stop 27 preventing contact of roll 25 with a glue roll 24. p

Each glue pot is supported by one of the bars 79 and the bar 31, a hook shaped lug 32 at one end of the box engaging the latter and a plain lug at the opposite end of the box restin upon the former. These glue pots are ad ustable on bars 79 and 31 toward and from each other when the rails 5 are adjusted. 1

After leaving the glue pot 23 the blank is enga d and carried forward at a greater epee than the chains 6 are moving by two pushers 33, Fig. 1, which, at the end of their feeding stroke. leave the blank in position to be operated upon by the folding mechanism. Each pusher 33 is a rod having a spring pressed latch 33" mounted at one end thereof and is slidably mounted in lugs upon the inner side of the adjacent chainsupporting rail 5. Each rod 33 has fastened on it a collar 34 made with :1 depending stud slidably engaging a bracket 35 which in turn is slidably mounted upon a bar 36. Each bar is carried by an arm 37 fulcrumed at 38 upon a rock-shaft that carries an arm 39 to which a slide bar 40 is connected. This slide bar is forked at one end and straddles a collar 41 on the main cam shaft 42, a cam roll on said slide bar bemg held against a cam 43 on said shaft by a spring.

After the blank is delivered to the folding mechanism by the pushers 33 a plunger 44 is lifted, carrying the blank upwardly against two plates 45 which overlap the body of the blank at their inner ends about a quarter of an inch. These plates serve as up-stops for the blank. See Figs. 10 and 11. When thus lifted by the plunger 44 a set of folders 46 wipe the side flaps C downwardly and at the same time a pair of members 47 Wipe the double end flaps A A downwardly. As the blank is thus lifted by the plunger 44 fingers 48 on the end folders or wipers 46 turn the small flaps B B downwardly just prior to the downward movement of the side flaps C and double end flaps A A so that when the end flaps A A are immediately thereafter turned downwardly by engagement with the wipers 47, said small flaps B B will be inside of the end flaps A A. After plunger 44 has reached its uppermost position and come to rest, a second plunger 49 is lifted. At the start of this movement of the second plunger 49 rolls 50 carried thereby act through arms 510 to move the wipers 47 inwardly, and the inner end of the latter act to bend the end flap sections A inwardly. Continued upward movement of the second plunger 49 causes jaws 51 at the upper end thereof to engage the inwardly bent end flap sections A and fold the same upwardly against the inturned small flaps B and B The jaws 51 are slidably mounted upon, and connected with, the top of a sleeve 52 that is normally urged upwardly by springs 53 surrounding rods 54 that are fast at their upper ends to said sleeve. These springs hear at one end against the sleeve 52 and at their 0 posite ends against lugs projecting from the second plunger 49. The rods 54 extend downwardly loosely through the lugs of plunger 49 and also loosely through lugs 55 projecting from the frame of the machine. Below the lugs 55 the rods 54 have stop nuts 56 mounted upon them. Stop collars 57 on rods 54 limit the upward movement of the latter under the influence of springs 53.

When the second plunger 49 is moved far enough upwardly to bring the stop nuts 56, against the lugs 55 on the frame, further upward movement of the sleeve 52 with said second plunger is prevented. and the continued upward movement of the second plunger thereafter causes the latter to act through toggle links 101 to shove the two jaws 51 outwardly to clamp the folded together flaps between said jaws 51 and plates or jaws 59. This outward clamping movement of the jaws 51 occurs when the latter have assed into position fully within the folde box. The plates or jaws 59 are secured to the inner ends of supports 60 that are adjustably mounted upon and clamped fixedly to a pair of cross bars 61 forming part of the frame of the machine. After the end flaps have been thus folded inwardly and pressed into intimate contact the top plates 45 are moved outwardly from their positions above the end portions of the box, and at about this time also, the second plunger 49 is moved downwardly sufficiently to draw together the jaws 51 so as to free the box. Immediately thereafter the first plunger 44 is given a further upward movement which carries the lower edges of the side flaps G into position just above spring pressed latches 62 carried by some of the wiper plates 46. Now, when the two plungers 44 and 49 move downwardly to their normal positions the latches 62 hold the box elevated and prevent it from following downward.

During the passage of the blank through the machine it is supported by the rails 5 and a pair of intermediate rails 102 said blank being held against upward displacement by rails 63 disposed above its path and connected by brackets with the rails 5.

Adjustable stops 64 limit the movement of the blank under the influence of the pus'hers 33 and position said blank with relation to the plunger 44. As each blank is moved forward by the pushers 33 it passes under a pair of spring detents 501 whose free ends spring downwardly slightly after the blank has passed and serve to prevent rebounding or return movement of said blank.

The top plates 45 of the folding mechanism are mounted upon small carriages 103 slidably mounted upon rods 104, said can riages being moved in one direction by springs 105 and in the opposite direction by cam wedges 106 provided at the ends of levers 66 which engage rolls on said carriages. The levers 66 have their hubs splined on a rock shaft 67, said hubs being located within forks provided upon the supports 60. Outside of one of the sideframes of the machine the shaft 67 is provided with an arm 68 to which is connected the upper end of a rod 107 provided at its lower end with a yoke embracing cam shaft 42 and carrying a cam roll engaged by a cam 69 on said shaft.

A cam 108 on cam shaft 42 acts through a leverarm109; rock shaft 110: lever arm 111 and link 112 to lift plunger 44, said plunger being returned to its normal lowermost position by gravity and a spring 113 connected with arm 111 while a cam 114 on said shaft acts through a lever arm 112 rock shaft 123; lever arm 124 and link 125 to control and operate the other plunger 49.-

The glue applying rolls 24 are splined upon a shaft 115 extending across the machine through both pots 23 and near one side of the machine said shaft has mounted thereon a gear 116 driven by a gear 117. The gear 117 is journalled upon a stud projecting from the adjacent side of the machine and is compounded with a sprocket 118. The chain 76, referred to above, extends around and drives this sprocket and the latter acts throughgears 116 and 117 to rotate shaft 115 and the glue rolls carried by it.

, The plunger 49 is a channel-iron shaped 2 bar slidably mounted in ways 120 on "the The main cam shaft 42 may be connected. [with a drive shaft 126 by a train of gear 127, 128, 129 and 130.

Side guide rails 131 adjustably supported adjacent the upper ends of the plungers prevent sidewise displacement of the blank as it is moved into position upon the top of plunger 44 by the pushers 33.

The rails '5 together with: parts carried thereby; the 'justifying members 7; the pairs of arms 21; 22; the glue pots 23; arms 66; supports 60; wiper plates 46;;side

guides 131; and wipers 17,-are all supported with provision for adjustment toward and from each other to adapt the machine to blanks of different sizes. The endstops 64 are also mounted upon a .cross bar 132 with provision for adjustment toward and? from the plungers for the same reason. a course in changing from one size of box'to another it will sometimes be necessary or desirable to substitute plates 45 and jaws 51 of appropriate width, and for this reason" saidparts are made removable.

A feature of advantage of my invention is that the corner flaps of the blank are bent down while the blank is moving. is saves time and gives better results, because the chains are guided and the blanks re: main accurately in position so that the bending elements strike the blank accurately.

Another feature of advantage 1 of my internal expansible plunger is that it makes perfect work and glvespositive control and results in increase of speed and no spoilage. Another feature of advantage is the qulck adjustment for different sizesof blanks which permits change of position of the feed rolls and of the folding arms. Another feature ofadvantageis that all moving parts are positive and accurate in their action.

Another featiire of advantage is that the roll 25 may be raised to permit the passage of two blanks in case, by accident, two blanks should be fed'together, one above the other. Otherfeatures ofadvantage will be clear proper outline and with foldable sections or flaps and creased to define the lines of fold. The term crease is employed as a generic term to mean any treatment of the sheet material which will facilitate the folding of the blanks onproper lines. 7

When the, machine illustrated is in use,

.the timing of the operation of the different parts is such that each blank (see Fig. 12) fed by the wheels 2 onto the rails 5 has its rear edge engaged by two pins of the chains 6, the blank then first travelling between the two jogging members 7 which act against the edges'of the sections A of the blank to laterally centralize or position it so that as the blank continues to travel the end flaps or'sections thereof will be accuratel alined with the parts of the machine which are to then apply glue to predetermined portions of the blank and break or fold said flaps" or sections. This jogging or positionungof the blank is important in cooperation with later actions of the machine on the blank, because it renders it certainfirst that the'breakers 16 will acton the end flaps or sections as hereinbefore described, at the 'nes ofsaidflapsYnext that the rotating arms 21, 22, will'act on the corner flaps B B at the proper and equal distances from their crease line's,"next that the two glue rolls 24 will apply glue to the proper lateral r areas'of the end flaps, and finallv'that the blank will arrive against the stops 64 in accurate lateral position to be acted upon by the finalfolding mechanism, so that the machine as a whole will effect true folding upon crease lines which existed in the blanks before being supplied to the machine, thereby avoiding any misfolding of the blanks. The operation of the final folding mechanism has been hereinbefore described.

In order to attain the best results it is essential that each blank delivered to the final foldingmechanism shall be accurately positioned longitudinally of the machine as well as laterally, especially in view of the fact that the blanks are creased in two directions, at right angles to each other. This is effected by the cooperation of the pushers "33 and the lateral-joggers 7. The latter,

and the chain pins'6'., ensure delivery of each blank in correct lateral position in front of the pushers, and aid pushers ensure correct positioning of t e blank longitudinally of the machine against the adjustable stops roper and equal distances from the crease 64, so that the creases of the blank will occupy correct positions relatively to the four sides of the final folding mechanism, to avoid folding on lines other than said creases.
